WATCH: [All Stars vs. Avalanche highlights]
The five-game winning streak is the longest of the season for the Stars, who improved to 7-1-0 over their last eight games and are now 16-10-1 on the season. The Stars, who were coming off a home-and-home series sweep of Chicago, kept the momentum going in Denver on Sunday.
"It's huge for our team," said defenseman Greg Pateryn. "We've done some good things and built off what we need to this past week and on the road. It was really important for us to close this week out."
"We're playing the right way," said Stars coach Ken Hitchcock. "There's no other way to describe it. We're playing the game the right way. We're not chasing the game up and down the ice. We're not gambling on 50-50 situations. We're playing smart. If you play the game the right way, and you have enough skill, then you give yourself a chance to win games. That's what we're doing."
The Stars got off to a good start Sunday, taking a 2-0 lead into the first intermission, maintaining a two-goal lead after 40 minutes and then putting the game away with three unanswered goals in the third.
Tyler Seguin and Brett Ritchie each scored two goals for the Stars. Jason Spezza, Pateryn, and Devin Shore scored as well. Kari Lehtonen, who was making his first start since Nov. 18, stopped 25 of 27 shots for Dallas.
"I think Lehtonen stood tall," Hitchcock said.
